I have the same problem and received advise from this board that it may be a relay problem. I purchased a new relay for $33, received it today and plan on installing it tonight. I'll post my results tomorrow morning.
BTW: The relay for the flashers is the same relay for the 4-ways.
Here's a link to the part:

Keep in mind that this is for a 2001 A4 2.8 Quattro.
